Physiological and biochemical studies on psychrotolerance in Listeria monocytogenes [PDF]
Journal of Applied Microbiology, 1997 Studies were undertaken to explain the ability of Listeria monocytogenes to grow at low temperatures in a chemostat. It was found that when grown in continuous culture at a dilution rate of 0.02 h-1 L. monocytogenes had a lower proportion of anteiso-17:0, and a higher proportion of anteiso-15:0, and smaller chain fatty acids when grown at 10 degrees C ...

Isolation and Characterization of Phenol-Degrading Psychrotolerant Yeasts [PDF]
Water, Air, & Soil Pollution, 2017 In this study, the potential of selected psychrotolerant yeast strains for phenol biodegradation was studied. From 39 strains isolated from soil and water samples from Rucianka peat bog, three psychrotolerant yeast strains, A011, B021, and L012, showed the ability to degrade phenol.

INCIDENCE AND ANTIBIOTIC RESISTANCE OF PSYCHROTOLERANT BACILLUS CEREUS GROUP IN ICE CREAM SAMPLES, WITH SPECIAL REFERENCE TO BACILLUS THURINGIENSIS [PDF]
Assiut Veterinary Medical Journal, 2011 Bacillus cereus causes food-poisoning by means of enterotoxins with either emetic or diarrheal effects. Hence, psychrotolerant Bacillus cereus group occurrence in 150 ice cream samples was investigated. Mannitol-egg yolk-polymyxin B (MYP) agar medium was
